is-posix-bracket
Advanced tools
Returns true if the given string is a POSIX bracket expression (POSIX character class).
The is-posix-bracket npm package is designed to check if a string includes a POSIX bracket expression. POSIX bracket expressions are a special kind of syntax used in regular expressions to define a range or class of characters to match. This package provides a simple utility function to detect these expressions in strings, which can be particularly useful when parsing or processing regular expressions or strings in applications that need to handle text patterns.
Detection of POSIX bracket expressions
This feature allows developers to check if a string contains a POSIX bracket expression. The function returns true if the string is a POSIX bracket expression, otherwise false. This is useful for validating or parsing regular expressions in text processing applications.
const isPosixBracket = require('is-posix-bracket');
console.log(isPosixBracket('[[:alpha:]]')); // true
console.log(isPosixBracket('[a-z]')); // falseMicromatch is a powerful globbing library that can match strings using the extended globbing syntax used by bash. It supports POSIX brackets and offers more comprehensive pattern matching capabilities compared to is-posix-bracket. Micromatch provides a broader set of features for matching complex patterns, making it suitable for applications requiring detailed control over string matching.
Matcher is a simple package that allows matching strings against a list of patterns. It supports basic wildcards but does not have built-in support for POSIX bracket expressions. Compared to is-posix-bracket, Matcher is more general-purpose and less specialized, suitable for simpler matching tasks where POSIX bracket detection is not required.
Returns true if the given string is a POSIX bracket expression (POSIX character class).
